摘　　要：为了有效去除矿井水中的盐分,降低其矿化度,以苯乙烯-二乙烯基苯共聚物SDB、1,4-环氧丁烷THF和乙二胺为主要原料,制备了一种适合矿井水除盐用的阳离子交换树脂LYH-01,并考察了不同因素对除盐效率的影响。结果表明:随着阳离子交换树脂LYH-01活化时间的延长、投加量的增大以及交换反应时间的延长,模拟矿井水的除盐效率均呈现出逐渐增大的趋势;而随着模拟矿井水初始矿化度的升高以及交换反应次数的增大,除盐效率则逐渐减小;另外,随着交换反应温度的不断升高,除盐效率则呈现出先增大后减小的趋势。阳离子交换树脂LYH-01还具有较强的再生能力,再生后的树脂除盐效率虽然略有降低,但在交换反应次数为2次时仍能使除盐效率达到73.6%,起到良好的除盐效果。In order to effectively remove salt from mine water and reduce its salinity,a cation exchange resin LYH-01 suitable for mine water desalination was prepared with styrene divinylbenzene copolymer SDB,1,4-epoxybutane THF and Ethylenediamine as main raw materials.The experimental results showed that as the activation time,dosage,and exchange reaction time of cation exchange resin LYH-01 extended,the desalination efficiency of simulated mine water showed a gradually increasing trend;As the initial mineralization degree of simulated mine water increased and the number of exchange reactions increased,the desalination efficiency gradually decreased;In addition,as the exchange reaction temperature continued to rise,the desalination efficiency showed a trend of first increasing and then decreasing.The cation exchange resin LYH-01 also had strong regeneration ability.Although the desalination efficiency of the regenerated resin slightly decreased,it could still achieve the desalination efficiency of 73.6%when the number of exchange reactions was 2,achieving good desalination effect.
